CROSS-REFERENCE TO RELATED APPLICATION(S)

This patent application is a continuation of and claims the benefit of priority to U.S. application Ser. No. 15/677,741, filed Aug. 15, 2017, the entirety of which is incorporated herein by reference.

TECHNICAL FIELD

Various embodiments of the present disclosure relate generally to an electronic payment infrastructure and, more particularly, to a message bus transmitting messages between components of an electronic payment infrastructure.

BACKGROUND

Traditionally, merchants and other store owners have point of sale (POS) terminals and POS systems that can accept check or payment card payments from consumers for goods and services. Such POS systems may include PIN pads at which a consumer may enter payment and/or personal information in order to complete payment processing requests for purchases. Communication between a POS terminal, a PIN Pad, and other components of the merchant's payment processing system may involve transmitting message according to different protocols and via different application programming interfaces (APIs). When a new component is added, the new protocols and APIs for the new component are typically added to the system. This may result in delays in adopting new components or difficulty in adapting to a merchant's existing equipment.

The present disclosure is directed to overcoming one or more of these above-referenced challenges.

DETAILED DESCRIPTION OF EMBODIMENTS

Various embodiments of the present disclosure relate generally to communication between components of an electronic transaction processing system.

The terminology used below may be interpreted in its broadest reasonable manner, even though it is being used in conjunction with a detailed description of certain specific examples of the present disclosure. Indeed, certain terms may even be emphasized below; however, any terminology intended to be interpreted in any restricted manner will be overtly and specifically defined as such in this Detailed Description section.

A merchant payment processing system may typically include one or more point of sale (POS) terminals in communication with one or more personal identification number (PIN) pads. Once a customer's transaction entered at the POS device is ready for completion, the POS device may send messages through the merchant's transaction processing system to a PIN pad. This interaction may include presentation of payment credentials, such as a payment vehicle, and entry of customer identification, such as a PIN, biometric information, etc. The PIN pad and other components of the transaction processing system may communicate by way of communications protocols and APIs specific to each component.

Desirably, in order to allow a flexible communication between a PIN pad, a POS device and other components, such communications may be processed by an intermediary process to transmit messages among the components. For example, the merchant's payment processing system may include a message bus that may operate on a common communications protocol. Thus, each component may avoid directly communicating with another component and may avoid necessarily having information about each component's communications protocols and APIs.

As shown in FIG. 6, in an electronic payment processing system, a consumer 602, during the checkout process with a merchant 610, pays for goods or services from merchant 610 at a PIN pad 128 associated with POS terminal 102. Consumer 602 may use a payment card as payment and the transaction is processed through a payment environment 600. Because merchant 610 generally can use a different bank or financial institution 640 than consumer 602, an acquirer processor 630 handles the financial transactions that transfer payment between the financial institution 640 of consumer 602 and that of merchant 610. Consumer 602 submits payment information at the PIN pad 128 associated with POS terminal 102 of merchant 610, such as by swiping his or her payment card, inserting his or her chip-based payment card, through wireless near field communication (NFC), etc., or by any other suitable means. PIN pad 128 sends a payment request by way of a computer network 625 to an acquirer processor 630. Alternatively, such a request may be sent by a component that controls a flow of a transaction, such as point of sale (POS) engine 106 depicted in FIG. 1. Acquirer processor 630 requests, by way of payment network 620, an electronic transfer of funds from the received funds to the financial institution 640 associated with merchant 610.

Merchant 610 may provide an infrastructure for processing electronic payment requests. FIGS. 1 and 2 depict an exemplary system infrastructure for payment processing within a merchant environment, according to one or more embodiments.

As shown in FIG. 1, an infrastructure 100 for processing electronic payment requests may include one or more point of sale (POS) devices 102, which may be in communication with a POS engine 106, and one or more personal identification number (PIN) pad terminals 128, which may be in communication with a socket gateway 124. POS devices 102 may communicate a sale request message over computer network 104 to POS engine 106. POS engine 106 may be embodied, for example, as middleware that may transmit commands to control a PIN pad 128, such as by sending a payment request to PIN pad transaction generator 110 over computer network 118. PIN pad transaction generator 110 may generate one or more PIN pad commands 114 for processing by a transaction generator 112. Transaction generator 112 may take in a transaction request from the POS engine 106 and PIN pad specific commands 114 for the transaction. Transaction generator 112 may further take in expected responses from PIN pad 128. Transaction generator 112 may manage the entire transaction using, for example, a state machine for the specific transaction. PIN pad transaction generator 110 will be described in greater detail below with respect to FIG. 2.

Infrastructure 100 for processing electronic payment requests may further include a PIN pad device gateway 120, which may provide commination with PIN pad terminals 128. PIN pad device gateway 120 may include a message broker that may process incoming sales transaction messages, a transaction service bus topic 122, and one or more device gateways 124.

As shown in FIG. 1, infrastructure 100 may further include a configuration management service 130, which may provide configuration services for PIN pad terminals 128. Configuration management service 130 may include a configuration service 140, a PIN pad registry 138, and a PIN pad database 142. Configuration service 140 may, if necessary, configure the PIN pad upon connection of the PIN pad to the infrastructure. PIN pad registry 138 and PIN pad database 142 may maintain data associating each PIN pad with an account or merchant. Configuration management service 130 may further include a lane management service 132 and a PIN Pad activator 134.

Infrastructure 100 may be embodied as a semi-integrated solution and may further control the PIN pad on behalf of the POS device software. Such control may include controlling a transaction flow or sequence including, for example, prompting for payment card swipe or insert, sending a transaction request for authorization, prompting for a consumer signature, etc.

Turning to FIG. 2, a system infrastructure 200 for cloud based messaging may be provided for communication between multiple components or services. As shown in FIG. 2, a service A (205) may send a message to a service B (240) by way of message bus pump 108. The message may be, for example, a text message, an encoded command message, a data structure, etc. Message bus pump 108 may include a message bus 230, which may contain one or more topics/messages 235. Service A may transmit the message to message bus pump 108 by way of communications network 210. Communications network 210 may be a cloud-based connection, a wired network, a wireless network, or any other kind of suitable communications network. The message may be transmitted to message bus 230 directly according to a native communications protocol of message bus 230, or it may be translated to such a protocol by protocol transaction service 215. In order to receive a message, service B may first register a topic with message bus pump 108 by way of topic registration service 220. Once a topic is registered, a topic listener 225 may wait for a message matching the registered topic to appear in message bus 230. Topic listener 225 may identify a message matching the registered topic by one of, for example, periodically polling message bus 230 for matching messages, registering a callback method to be called by the message bus 230 when a matching message is received, etc. When a matching message is found, topic listener 235 may transmit the message to service B by way of communications network 245. Communications network 245 may be a cloud-based connection, a wired network, a wireless network, or any other kind of suitable communications network. The message may be transmitted from message bus 230 directly according to a native communications protocol of message bus 230, or it may be translated to an appropriate protocol for service B by protocol transaction service 215.

Services utilizing message bus pump 108, such as service A (205) and service B (240), may be grouped into zones comprising services providing related services or services that are geographically or logically co-located. For example, services related to point of sale (POS) terminals may comprise a particular zone. In addition, services operating for a particular merchant or at a particular merchant location may comprise a particular zone. In one or more embodiments, message bus pump 108 may transmit messages only between services operating in different zones.

At operation 320, message bus pump 108 may receive a message and message topic from a message sender, such as service A (210) depicted in FIG. 3. At operation 325, message bus pump 108 may translate a message from a sender protocol to a message bus protocol. Such a translation may be performed by a protocol translation service, such as protocol translation service 215 depicted in FIG. 3. At operation 330, message bus pump 108 may store the message topic and message on the message queue. At operation 335, message bus pump 108 may identify a message matching the registered message topic on message queue. Such recognition may be performed by a topic listener, such as topic listener 225 depicted in FIG. 3. At operation 340, message bus pump 108 may retrieve the matching message from the message queue. At operation 345, message bus pump 108 may translate the message from the message bus protocol to a recipient protocol. Such a translation may be performed by a protocol translation service, such as protocol translation service 215 depicted in FIG. 3. At operation 350, message bus pump 108 may transmit the translated message to the recipient.

FIG. 4 depicts a communication flow diagram of a method of cloud based messaging, according to one or more embodiments. As shown in FIG. 4, at operation 402, a recipient, such as service B (240) depicted in FIG. 3, may send a topic registration request to a message bus pump. In operation 404, the message bus pump may register the requested topic for the recipient. In operation 406, the message bus pump may listen for the registered topic on the message queue. Such listening may be performed by a topic listener, such as topic listener 225 depicted in FIG. 3. In operation 408, a sender may send a message and a message topic to the message bus pump. In operation 410, the message bus pump may translate the message to a message bus protocol. Such a translation may be performed by a protocol translation service, such as protocol translation service 215 depicted in FIG. 3. In operation 412, the message bus pump may store the translated message and the topic on a message queue. In operation 414, the message bus pump may identify registered message topic on message queue. In operation 416, the message bus pump may retrieve the message from the message queue. In operation 420, the message bus pump may translate the message from a message bus protocol to a recipient protocol. Such a translation may be performed by a protocol translation service, such as protocol translation service 215 depicted in FIG. 3. In operation 422, the message bus pump may transmit translated message to recipient.

FIG. 5 depicts a flowchart of a method of cloud based messaging, according to one or more embodiments. As shown in FIG. 5, at operation 510, a message recipient may send a topic registration request to the message bus pump. At operation 520, the message recipient may receive a message from the message bus pump. At operation 530, the message recipient may translate the received message from a message bus pump protocol to a local protocol. Such a translation may be alternatively be performed by a protocol translation service, such as protocol translation service 215 depicted in FIG. 3. At operation 540, the message recipient may generate a response message. At operation 550, the message recipient may translate the response message to a message bus pump protocol. Such a translation may be alternatively be performed by a protocol translation service. At operation 560, the message recipient may transmit the response message and the response message topic to the message bus pump.
